| description | The utility model relates to the technical field of dredging dredge pump hydraulic design, in particular to a low-lift dredge pump impeller, which is a cantilever type closed centrifugal impeller, and comprises an impeller front cover plate (1), a flow guide cap (2), a blade group, an impeller rear cover plate (4) and a hub (5), and the impeller front cover plate (1), the flow guide cap (2), the blade group, the impeller rear cover plate (4) and the hub (5) define an impeller overflowing part. The blade set is composed of special blades (3), the blades (3) are twisted blades, the number of the blades is three, and the blades are evenly distributed on the circumference. The lift of the dredge pump designed by adopting the impeller is reduced by 20m compared with that of a general impeller, the efficiency reaches 86%, and compared with the implementation effect of adopting a pipeline necking, the unit energy consumption is reduced by more than 10% under the working condition of short row pitch, the fuel consump |
